Definitions

  • the present invention relates to a plant for continuous spreading on textile, paper and similar materials.
  • One object of the present invention is to provide a plant allowing the spreading on each side of the sublayer.
  • a further object of the invention is to provide a steady monitoring of the actual consumption of the product intended to coat the sublayer.
  • an object of the present invention is to allow a complete automation of the plant's washing by utilizing substantially the same means used for feeding the substances to be distributed over the substrate.
  • the advantages deriving from the present invention lie essentially in that it is possible to apply the coating product over the whole surface of the sublayer, such as, for example, over yarns, ribbons or rolls of fabric, webs of paper material and the like, in a relatively simple, fast, economical and reliable manner; that it is possible to evaluate, with extreme accuracy and at any moment, the consumption of the coating material, thereby allowing also to check for any possible plant's operation anomaly and to feed the coating material with the necessary precision and according to specific work requirements; that it is possible to automate the washing cycle of the plant and to use, for this purpose, the same means adopted for the feeding of the coating material.
  • Fig. 1 shows a diagram of a plant according to the invention
  • Fig. 2 shows schematically the side view of a machine for waxing textile materials which is provided with a plant according to the invention.
  • a plant for continuous spreading on a textile, paper or similar sublayer comprises in combination:
  • Fig. 1 of the attached drawings the upper chambers of the tanks (1, 1') are denoted by the letters (U) and respectively (U') and the lower chambers are denoted by the letters (L) and respectively (L').
  • a third roller (22) engaged to corresponding motion means, such as an actuator cylinder, and mounted on a slide with vertical axis (23), on which the sublayer (S) rests when exiting from said first roller (2), so as to operate, with the displacement of the roller (23) along the axis of the supporting slide (22), the release of the sublayer (S) out of contact with one or both the spreading rollers (2, 2').
  • corresponding motion means such as an actuator cylinder
  • the said tanks (1) and (1') are connected to the container (4) of the coating material through a conduit intercepted by a pneumatic valve (12) so as to allow, upon command, the emptying of the tanks (1, 1') and the return of the held-therein liquid to the container (4).
  • the said valve (12) being in closed condition during the operating step of the plant, and in open condition during the emptying of tanks (1, 1').
  • an ultrasound sensor (13) for the istantaneous detection of the bath level within said container (4).
  • a corresponding sensor for measuring the humidity degree of the sublayer (S), so as to evaluate exactly the difference between the humidity degree of the sublayer (S) upon its entry to, and exit from the plant.
  • a recovery container (14) connected to the container (4) of the coating material through a conduit (15) provided with an intercepting valve (16) to allow the recovery of the bath whenever the container (4) is to be emptied, such as during the plant's washing stage to be described below.
  • the said second pump (7) is advantageously connected, by means of a conduit (18) provided with an intercepting valve (19), to a container (20) holding the liquid for the washing of the tanks, containers and conduits of the plant.
  • a tap (21) interposed between the said first pump (3) and the upper chamber of said first tank (1) to allow for the adjustment, in a differentiated manner, of the flow of coating material from the first pump (3) to the tanks (1) and (1').
  • a conduit (not shown) may be advantageously provided, having an "Y" branch for feeding the upper chambers of the two tanks (1, 1').
  • the plant's valves and pumps are operable by programmable electronic means known per se to those skilled in the industrial automation, and will not therefore be described in detail. The operation of the above described plant is as follows.
  • the container (4) is fed by the pump (7) which draw by suction the bath from the container (8).
  • the upper chamber of the tanks (1, 1') are fed continuously by the pump (3) which draw by suction the bath from the container (4), the latter thereby acting as a plenum chamber of the bath-feeding means.
  • the amount of product fed into the lower tank (1) may be metered by means of the tap (21).
  • the continuous detection of the consumption of the coating material is made through the level sensor (13). This allows adjusting in a corresponding manner the rotation speed of the rollers (2, 2'), calibrating the instruments - known per se - measuring the current hunidity degree of the treated sublayer, and adjusting the flowrate of the pump (3).
  • each tank (1, 1') makes it possible to continuously refresh the bath of coating material laid onto the sublayer (S) by the rollers (2, 2').
  • the washing of the plant is made by emptying the tanks (1, 1') with the valve (12) in open condition, and then closing the valve (17) and opening the valve (19), thereby aspirating the washing liquid from the container (20) and putting it in circulation within the plant's conduits by means of the pumps (6, 7).
  • the sublayer (S) consists of a textile yarn unwinding from a reel carried by a known per se feeding group (T).
  • the coating material is a bath of liquid wax for the waxing of the yarn.
  • the yarn On its exit from the spreading roller of the upper tank (1'), which in the present example acts as a waxing roller in cooperation with the lower tank (1), the yarn is fed to a drying apparatus (A) of the type described in the Italian patent application No. FI95A171.
  • Said apparatus (A) is mounted on a frame comprising two stanchions (24) to which two fixed, parallel, horizontal brackets (25) are mounted and each of which supports a corresponding tank (1, 1').
  • the amount of coating material which can be distributed over the sublayer (S) is variable also in relation to the speed of rotation of the spreading rollers (2, 2') and to the feeding speed of the sublayer (S).
  • materials of other type such as ribbons or rolls of fabric, webs of paper materials, yarns or bands of synthetic materials or woven and not woven composites, may be treated in an equivalent way, and that the coating material may be however different from the wax, provided it is suitable for spreading a continuous coat on the sublayer.
